Air Compressor

How to choose the best air compressor for my workshop?

The use of one or another type of air compressor will depend on the needs of the installation in terms of flow and pressure of the compressed air, it is also important to know the field of application of each type of compressor, to choose the most appropriate.

What kind of air compressor to choose:

The requirements of flow and compressed air pressure lead to choosing the power of the compressor, since each compressor is capable of guaranteeing a flow rate and a certain pressure with a different power.

To calculate the air flow you need to add the flow of every pneumatic tool to individual , which results in the maximum needs of air flow, and applying some coefficients to adapt the maximum theoretical consumption to the reality of each workshop, because not all the equipment works simultaneously.

We should not choose only for the price since cheap air compressors can cost us more in the long run.

Example:

Small air compressor in a car repair shop and to paint.
